PRINTING-PLATE HOLDER.

SPECIFICATIQN forming part of Letters Patent No. 551,457, dated December 1*?, 1895. Application filed May 31, 1895. Serial No.' 551,084l (No model.)

To aZI/ whom t may concern:A be formed integral with the plate or secured Be it known that I, EDWIN D. TUCKER,a thereto in any suitable manner, as by being citizen of the United States, residing at New carried by plates c (Z secured to the plate or York, county of New York, and State of New bar 15, between which clips there is left a 55 5 York, have invented certain new and useful recess or space c -to permit of operating, as Improvements in Printing-Plate Holders, by the insertion lof a suitable instrument, a fully described and represented in the follow screw 16 by which the plate is held to and ing specification and the accompanying drawadjusted toward and away from the block and ings, forming a part of the same. the head of which lies against the plate or 6o 1o rlhis invention relates to plate-holders for bar 15 between the clips. The screwl passes stereotype or other printing plates, and aims loosely through the plate or bar and screws to provide a plate-holder which shall occupy into a threaded recess 17 in the block, and is a minimum of space between the plates, and provided inside the plate 15 with a shoulder shall yet be strong and efficient and conven- 1,8, which is preferablyapin, as shown, pass- 65 I 5 ient to use; `and the invention aims further ing through the screw, and which may be reto provide a plate-holder which will allow of moved to allow of ready removal of the parts, such slight adjustment of the plates on the and is provided on its outer end with a head block or blocks as may be necessary, as for 19 which is preferably out to forni a pinion', as the purpose of causing the impression from shown. Thus byturningthe screwlG one way 7o 2o the plates to register with previous impresor the other the plate or bar 15 carrying' the sions. clips a and Z9 will be advanced or retracted. The invention consists, therefore, of various It will be seen that this construction provides constructions and combinations of parts, as a very strong and conveniently-operated will be hereinafter specificallyT pointed out clampingdevicewhichoccupiesbutverylittle 75 in the claims, and for a full understanding of space between the blocks, the head 19 of the which a detailed description will now be adjusting-screw lying close against the plate given of a construction embodying the same 15 between the clips and extending little, if in a preferred form and illustrated in the acany, farther out from the plate than the clips, companying drawings, in whichand the space c between the clips permitting 8o 3o Figure 1 is a plan view showing a block the head 19 to be conveniently turned, as by provided with a construction embodying the a rack, such as is usually employed for the invention and havingaplate secured thereto purpose, or 'any other suitable instrument. and indicating adjacent blocks. Fig. 2 is a The opposing face ofthe adjoining block is section on line 2 of Fig. l. Fig. 3 is a section preferably provided with two stationary clips 85 on line 3 of Fig. 1. Fig. /tis a view taken on f g placed at or near either end, leaving beline a of Fig.V 1. Fig. 5 is a view taken on tween them a space 7i corresponding to the line 5 of Fig. 1.

WWith this arrangement, even when the ively, the blocks, however, beingmounted on head 19 of the adjusting-screw extends far- 9o 4o a cylindrical surface.

On one of its remaining sides movable clips. Y each block is provided with a device con- In the drawings the plate or bar15 is shown structed as follows: Aplate or bar 15 eXtendas extending the full length and depth of one ing preferably entirely across one side of the side of the block; but it will be understood roo 5o block, the block being cut away to receive that the plate or bar may be made of any said plate or bar, carries clips ab, which may other suitable proportionate size or form to serve as a support for the clips a l), as it may be proportionately either shorter or narrower, or both, the block being then correspondingly lrecessed to receive the plate and allow of its proper adjustment, as will be readily understood.

It will also be understood that various other changes in the construction shown may be made without departing from the inventionas, for example, other means for advancing and retracting the plate or bar l5 may be employed; but the means shown is preferred and forms in connection with other features part of the invention.

lVhile the drawings show two clips with the space c between them, it will be understood that the plate or bar may be provided with any desired number, one er more, of clips alternating with spaces c.

Fig. lO shows a plate provided with two adjusting-screws and a single clip between the screws, this being considered an equivalent construction in most respects to that shown in the other views, as the heads of the adjusting-screws can lie close against the plate or bar and can be conveniently reached for adjusting the plate or bar. The remaining side of the block may also be provided with similarly-mounted adjustable clips, and will preferably be so when4 it is desired to economize space to the same extent on both sides of the block; but it frequently happens that it is not necessary to economize space to the same extent in one direction of the block as in the other, as when it is not necessary that the plates be mounted so closely together in one direction as in the other. This is so, for example, in printing playing-cards, the margins left at the ends of the cards being wider than those left at the sides thereof. 1n such cases the remaining side of the block may be provided with any suitable form of movable clip-such, for example, as those shown in the drawings 5 and I prefer to provide on such remaining side of the block two such adjustable clips ij, thus providing` a convenient arrangement for adjusting to a slight extent the position of the plate on the block, such as may be necessary for causing the impression to be taken therefrom to register with previo us impressions, such adjustment being readily made by inserting suitable paper or other wedges or slips between the plate and the stationary clips, the clips t' jon beingthen screwed down accommodating themselves to the position of the plate. rlhe plate or bar 15 is preferably a little loose on the screw 1G, so that it may also accommodate itself to the position of the plate.

As shown, the clips i j are carried by plates which are loosely mounted on longitudinallymoving screws 2O screwing into threaded holes 2l in the block, said screws being` provided on theinside of the plates carrying the clips with shoulders 22, which are preferably pins passing through the screws, as shown, and on the outside of said plates with heads 23, which are preferably cut to form pinions, as shown.

lt will be understood that the invention may be employed and will be found useful not only where it is desired to secure plates to separate blocks placed close together, as shown in the drawings, but also in other cases where .it is desired to economize space, and any such application of the principle of the invention is to be considered as within the scope of the claims.
